Making agents as a way to bound data is a useful pattern.

Claude Code does this a lot, spinning up little sub-agents that are isolated from the main flow often.

The agent is a secure little compute environment that bounds what data it can see.

That makes it so the reasoning doesn't muddy up the main context window, and vice versa.

In complex adaptive systems, boundaries always emerge to handle the compounding cacophony.

This reverse engineering of Claude Code by Simon Willison is fascinating.
